Surface mesh
MMO mesh can distribute current beneath a compatible overlay where broad surface coverage is required.
CONCRETE ICCP · MMO MESH, RIBBON & DISCRETE ANODES
MMO Anode Systems for Reinforced Concrete Cathodic Protection
Project-configured MMO titanium anode systems for chloride-contaminated or at-risk reinforced concrete in bridges, parking structures, marine assets and industrial facilities.
Engineering Note: Concrete condition, reinforcement continuity, cover depth, repair scope and zoning must be assessed by the responsible engineer before anode layout and current density are confirmed.

APPLICATION BASIS
How Reinforced Concrete ICCP Protection Works
In reinforced-concrete ICCP, the embedded steel reinforcement is the cathode and an MMO titanium system distributes current through the concrete electrolyte. The anode can be installed in an overlay, groove, repair zone, drilled recess or project-specific mounting arrangement, with reference electrodes and test points used for control and verification.
The system must address chloride distribution, concrete resistivity, moisture, cover, electrical continuity, delamination and repair interfaces. The anode manufacturer needs the approved zoning, geometry and connection details; the structural and CP designers retain responsibility for assessment and protection criteria.
SELECTION FRAMEWORK
Choose Mesh, Ribbon or Discrete ICCP Anodes
Match the anode form to the concrete condition, repair method, accessible surface and required current distribution.
Ribbon in grooves
Ribbon or mesh-ribbon can follow designed slots or strips with controlled spacing and connection details.
Wire arrangement
MMO wire can be routed through approved channels or localized zones where geometry favors a flexible element.
Discrete anodes
Disc or custom elements can serve localized repairs, columns, beams or complex zones under an engineered layout.
ANODE OPTIONS
MMO Anode Forms for Concrete ICCP
The system type must be compatible with concrete repair materials, placement tolerances, current distribution and monitoring strategy.
MMO Wire Anode
Best considered when: Flexible routing is required in grooves, channels or project-defined localized zones.
Confirm: Wire geometry, active length, spacing, connections, cover and repair material.
MMO Mesh Ribbon
Best considered when: A strip or distributed mesh layout is integrated with a compatible overlay or repair system.
Confirm: Mesh size, strip width, fixing, crossings, connector tabs and overlay interface.
MMO Ribbon Anode
Best considered when: Low-profile ribbon runs are specified for grooves, strips or zoned concrete surfaces.
Confirm: Ribbon size, coating/loading, spacing, joints, routing and cover depth.
MMO Disc Anode
Best considered when: Discrete elements suit localized zones or a designed array in complex concrete geometry.
Confirm: Disc size, connection, recess detail, fixing, backfill/encapsulation and cable route.
CONFIGURATION LOGIC
New Construction vs Concrete Rehabilitation
New construction allows anode and monitoring interfaces to be coordinated with reinforcement and concrete placement. Rehabilitation begins with condition assessment, contaminated-concrete removal, repairs and continuity checks before the anode zone is installed. The drawing should define zones, connection points, overlay or repair materials, cover and reference-electrode locations.
Design Control Boundary
The anode system does not replace structural assessment or concrete repair design. Compatibility with repair materials and protection criteria must be approved for the project.
ENGINEERING MATRIX
Concrete ICCP Assessment and Supply Inputs
The following items define the supply basis. Final values are confirmed by the cathodic-protection designer and project review.
| Decision | Why it matters | Evidence to provide |
|---|---|---|
| Concrete condition | Controls repair preparation and current distribution across the structure. | Condition survey, delamination map, cracks, resistivity and moisture. |
| Chloride exposure | Supports risk assessment, targeted zoning and current density selection. | Chloride profile, exposure history and contaminated depth. |
| Reinforcement | Continuity and geometry dictate the effectiveness of the cathode network. | Rebar drawings, cover survey and continuity test plan/results. |
| Anode zone | Defines the physical anode element form, spacing, connections and rating. | Zone drawings, current demand, anode layout and design life. |
| Repair interface | Materials and sequence directly affect anode embedding and long-term stability. | Repair/overlay specification, groove or recess details and curing sequence. |
| Monitoring | Provides the feedback loop for controlled operation and protection verification. | Reference electrodes, decay/criteria basis, test points and zoning. |
PROJECT INPUTS
Data Required Before Manufacture
- Structure drawings, accessible surfaces and defined repair zones
- Concrete resistivity, chloride profile, cover and condition data

- Record zone continuity, insulation checks, photos and as-built details
SUPPLY BOUNDARY
Anode Supply vs Complete CP System Responsibility
Define responsibilities in the purchase specification. HELE can configure and manufacture agreed anode components or assemblies; complete system engineering is not automatically included.
HELE supply can include
- MMO wire, ribbon, mesh-ribbon, disc or custom anode elements
- Factory leads, connector tabs and agreed termination hardware
- Project-specific prefabricated sections or assemblies
- Drawings, inspection records and agreed traceability package
Confirm separately in the contract
- Structural assessment and concrete repair design
- Final CP current density, zoning and protection criteria
- Repair mortar/overlay installation and site workmanship
- Power, monitoring, commissioning and long-term operation unless contracted

FAQ
Reinforced Concrete ICCP Questions
Which MMO anode form is used for reinforced concrete?
Mesh, mesh-ribbon, ribbon, wire and discrete anodes can all be used. Selection depends on the structure, accessible surface, repair method, required distribution, cover, zones and monitoring design.
Can ICCP anodes be installed during concrete rehabilitation?
Yes. The project must first define removal and repair areas, reinforcement continuity, concrete condition, compatible repair materials, anode zones and installation sequence.
What concrete data should be provided to the anode supplier?
Provide condition and chloride information, resistivity, cover, reinforcement drawings, repair details, zones, current demand, anode layout, connection details and monitoring requirements.
How are anodes prevented from shorting to reinforcement?
The issued detail and site QA must maintain separation, verify fixing and cover, inspect connections and perform the specified electrical checks before the anode is covered.
Does HELE set the protection criteria for the concrete structure?
No. Protection criteria, current density, zoning and monitoring interpretation are confirmed by the responsible CP and structural engineers unless a wider engineering scope is contracted.
